Wiseco Ford DOHC V8 4.6L 3 Valve NA/Boost/Nitrous Top Ring Down .300in -20.0cc 3.572 Bore 8.2:1 CR

Forged from 2618 aluminum, these Wiseco Professional Series pistons are built for serious Ford DOHC V8 4.6L 3-valve engines, whether you're running naturally aspirated, boosted, or nitrous applications. The 2618 aluminum alloy offers improved tensile strength, making these pistons well-suited for the demands of heavy to severe duty performance builds where reliability is paramount.

Wiseco has packed these pistons with features to handle extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined, and forced pin oiling helps keep the wrist pins lubricated. Additionally, the ArmorGlide skirt coating reduces friction, resists seizure, and contributes to quieter operation, which is a notable benefit when you're pushing an engine hard.

This set includes eight pistons, each with a 3.572-inch bore and a -20.0cc dish volume, resulting in an 8.2:1 compression ratio. The top ring is positioned down .300 inches. These pistons are designed and manufactured in the USA. Please note that this part is not CARB approved and cannot be shipped to California.
